I suspect the 9V1 specified yours as black

Often special order and fleet colors will not have a regular color code listed

I think the Chevy Sport in 77 was available in Black or Lite Blue

I had a lite blue one in 77 but it is long gone

if anyone out there has a lite blue 77 scottsdale short bed ......

It may have the other code

As you noted the actual COPO was 9J8

Again ...going from memory you could actually get a "double COPO" truck by ordering 9J9 to get the "sport rail"

What the rest of the world called a roll bar
